The qca (Bluetooth) and qcom (non-zap GPU) firmware blobs don't need to
be signed by the OEM, so let's use upstream versions to benefit from
fixes and updates done there.
It makes more sense here as it's also signed by OnePlus (instead of
just Qualcomm) and is expected to be here since
linux-postmarketos-qcom-msm8998>=5.16.0_rc6.
Add proprietary firmware required by OnePlus 5/5T's WLAN, Bluetooth, GPU
and other SoC subsystems such as ADSP. These are extracted directly from
OnePlus' OxygenOS 10.0.1 stock firmware with oos_fw_extract in the repo.
